MBP battery dyeing - circa 2006 | Thread profile

Lately my MacBook has been shutting down unexpectedly when the battery gets sort of low and I don't get any warning. The first time it happened at about 12 % and then at about 15%, 21% and again at 30%. It runs fine when plugged in. Battery health in System Profile says it has 286 cycles and to check battery. Does the hardware test on the install disk check the battery? I've ...

Load cycles - 290 The MBP is 28 months old, but the battery is about 6-7 months younger. This morning at work I wasn't watching the charge indicator as closely as I should have. I actually got down to 16% ...
